Despite the noteworthy migration rate, FCSEMSs should be considered effective for refractory benign biliary strictures. Further studies are needed to assess their role as a first approach in the management of BBS.

For endotherapy of biliary complications after orthotopic liver transplantation, metallic stents should not be used as the primary modality. In patients in whom the standard approach fails, treatment with temporary SEMS placement can solve biliary complications in almost three-quarters of cases; however stent migration(33 %) remains a problem.

Cystic lesions of the pancreas are being diagnosed with increasing frequency, covering a vast spectrum from benign to malignant and invasive lesions. Numerous investigations can be done to discriminate between benign and non-evolutive lesions from those that require surgery. At the moment, there is no single test that will allow a correct diagnosis in all cases. Endoscopic ultrasound (EUS) morphology, cyst fluid analysis and cytohistology with EUS-guided fine needle aspiration can aid in this difficult diagnosis.
